DSCR
Debt Service Coverage Ratio (DSCR) is a financial metric used by lenders to assess the ability of a company to cover its debt obligations.
Understanding DSCR
Debt Service Coverage Ratio (DSCR) measures a property's ability to cover its mortgage payments from operating income. It is calculated by dividing Net Operating Income by Annual Debt Service. A DSCR of 1.25x means the property generates 25% more income than needed to service its debt-providing a safety cushion for both the borrower and lender.
DSCR is the single most important metric lenders use to size commercial real estate loans. Most conventional lenders require a minimum DSCR of 1.20-1.25x, meaning the maximum loan amount is the point where debt service equals 80-83% of NOI. CMBS lenders may accept slightly lower DSCRs (1.15-1.20x), while conservative lenders and SBA loans may require 1.30x+.
For NNN properties, DSCR calculations benefit from the lease structure's income predictability. Lenders view long-term NNN leases with investment-grade tenants as lower risk, which can support slightly lower DSCR thresholds. However, lenders also stress-test DSCRs by applying higher interest rates to the calculation, ensuring the property can withstand rate increases at refinancing.
DSCR deterioration is a critical risk factor. If NOI declines (tenant vacancy, rent abatement) or debt service increases (rate reset on variable-rate loans, refinancing at higher rates), the DSCR may fall below lender covenants, triggering loan default provisions including cash sweep mechanisms, additional reserve requirements, or acceleration clauses.
Why DSCR Matters to Investors
DSCR determines how much you can borrow against your NNN property. A higher DSCR means more income cushion but also means you're using less leverage-potentially reducing equity returns. Most NNN investors target a 1.25-1.30x DSCR as a balance between leverage optimization and safety. In the current lending environment, stress-tested DSCRs (calculated at higher assumed rates) have become the binding constraint on loan sizing, often limiting proceeds more than LTV ratios.

Frequently Asked Questions
What DSCR do lenders require for NNN properties?
Most conventional lenders require 1.20-1.25x DSCR for NNN properties. Credit tenant NNN properties with long lease terms may qualify at 1.15-1.20x. CMBS lenders typically require 1.20-1.30x. SBA loans generally require 1.25x+. The actual requirement depends on tenant credit quality, remaining lease term, and the lender's risk appetite.
How does DSCR affect loan sizing?
DSCR is the primary constraint on loan proceeds. Maximum loan amount = NOI ÷ (Required DSCR × Annual Debt Service Constant). For example, with $150,000 NOI, 1.25x required DSCR, and a 7.5% debt constant, maximum ADS = $120,000 and maximum loan ≈ $1,600,000. In the current rate environment, DSCR often limits loan proceeds more than LTV.
What happens when DSCR falls below the lender's minimum?
When DSCR falls below the loan covenant (typically 1.10-1.15x), it triggers remedies including cash sweep (excess cash flow diverted to reserves), additional collateral requirements, increased reporting obligations, or in severe cases, loan acceleration. Persistent DSCR covenant violations can lead to loan default and potential foreclosure.
How do you improve DSCR on a NNN property?
Improve DSCR by increasing NOI (negotiate higher rent at renewal, reduce non-recoverable expenses) or decreasing debt service (refinance at lower rates, make additional principal payments, extend amortization period). Paying down the loan balance directly improves DSCR because it reduces the monthly payment while NOI remains constant.
